This page is for listing and discussing possible copyright problems involving text on Wikipedia, including pages which are suspected to be copyright violations. For images and text that are clear copyright violations, follow the procedure for speedy deletion; list images that are suspected to be copyright violations at possibly unfree images and images with disputed fair use rationales at Non-free content review. To request assistance with contributors who have infringed copyright in multiple articles or files, see Wikipedia:Contributor copyright investigations.

Generally, pages that are listed here are first blanked in whole or in part and tagged with the appropriate template (see instructions, below). In addition, the contributor of the content, if identifiable, should be notified of the concerns. Listings typically remain for seven days before review and closure by an administrator. During this time, interested contributors are invited to offer feedback about the problem at the relevant talk page, to propose revisions to the material or to request copyright permission. After the seven day listing period, an administrator will review the listing and take what further action may be necessary. සැකිල්ල:TOC Limit

If you believe Wikipedia is infringing your copyright, you may request immediate removal of the copyright violation. Alternatively, you may contact Wikipedia's designated agent under the terms of the Online Copyright Infringement Liability Limitation Act.


If you submitted work to Wikipedia which you had previously published (especially online), and your submission was marked as a potential infringement of copyright, then stating on the article's talk page that you are the copyright holder of the work, while not likely to prevent deletion, helps. It is sufficient to either:

See also Wikipedia:Donating copyrighted materials.

What's copyrighted?


Copyright is automatically assumed as soon as any content (text or other media) is created in a physical form. An author does not need to apply for or even claim copyright for a copyright to exist. Only an explicit statement (by the author or the holder of the rights to the work) that the material is either:

allows works to be reused in Wikimedia projects under current policy, unless it is inherently in the public domain due to age or source.

What about fair use?


Under guidelines for non-free content, brief selections of copyrighted text may be used, but only if clearly marked and with full attribution.

If you see an article somewhere else which was copied from Wikipedia without attribution, visit the CC-BY-SA compliance page or meta:Non-compliant site coordination.

Purge server cache if recent edits are not visible.


Wikipedia will naturally refer to and include some material that comes from outside sources. This material may be in the public domain, may be included under a fair use argument, or it may be under a license compatible with the license used on Wikipedia. Even when material is not covered by copyright, it is still important to state its origin, including its authors or creators. Failure to include the origin of a work is misleading and also makes it more difficult for readers and editors to refer to the material's source. It may also violate the terms of the Creative Commons Attribution/Share-Alike License.

Material that is plagiarised but which does not otherwise violate copyright does not need to be removed from Wikipedia if it can be properly sourced. See Wikipedia:Plagiarism for steps for addressing plagiarised material and editors who have copied text or figures into Wikipedia without proper attribution. Editors engaged in ongoing plagiarism who do not respond to polite requests may be blocked from editing.


Contributors who repeatedly post copyrighted material may be subject to contributor copyright investigations to help ensure that all copyrighted material placed outside of policy on the project has been removed. Contributors who repeatedly post copyrighted material after appropriate warnings will be blocked from editing to protect the project, see 17 United States Code 512.

Material whose presence on Wikipedia infringes copyright (ie. the material is not Public Domain, licensed under the Creative Commons Attribution/Share-Alike License, or specifically licensed to Wikipedia on suitable terms) should, as a general rule, be removed.

Blatant copyright infringements may be speedily deleted if:
  • Material was copied from a source which does not have a license compatible with Wikipedia;
  • There is no non-infringing content in the page history worth saving.
  • The text on Wikipedia really is an infringement of another source (Wikipedia has numerous mirrors — Make sure we're copying someone else, not the other way around)
  • Uploader does not assert permission, or the assertion is questionable

After notifying the uploading editor, add one of these to the page:

{{db-copyvio | url=insert URL of source here}}
{{db-copyvio | describe non-web source here}}

An administrator will examine the article and decide whether to delete it or not. You should not blank the page in this instance.

If infringement is not blatant or the speedy deletion criteria do not apply:

  • Remove the infringing text or revert the page to a non-copyrighted version if you can
    The infringing text will remain in the page history for archival reasons unless the copyright holder asks the Wikimedia Foundation to remove it. Please note the reason for removal in edit summary and at the article's talk page (you may wish to use {{subst:cclean}}). When possible, please identify and alert the contributor of the material to the problem. The template {{Uw-copyright}} may be used for this purpose.
  • However, if all revisions have copyright problems, the removal of the copyright problem is contested, or reversion/removal is otherwise complex:
    • Replace the text with one of the following:
      {{subst:copyvio | url=insert URL here}}
      {{subst:copyvio | identify non-web source here}}
    • Go to today's section and add
      * {{subst:article-cv | PageName}} from [insert URL or identify non-web source here] ~~~~
to the bottom of the list. Put the page's name in place of "PageName". If you do not have a URL, enter a description of the source. (This text can be copied from the top of the template after substituting it and the page name and url will be filled for you)
  • Advise the contributor of the material at their talk page. The template on the now blanked page supplies a notice you may use for that purpose.
  • You're done!

Instructions for special cases

  • Probable copyvios without a known source: If you suspect that an article contains a copyright violation, but you cannot find a source for the violation (so you can't be sure that it's a violation), do not list it here. Instead, place {{cv-unsure|~~~|2=FULL_URL}} on the article's talk page, but replace FULL_URL with the full URL of the article version that you believe contains a violation. (To determine the URL, click on "Permanent link" in the toolbox area, and copy the URL.)
  • Instances where one contributor has verifiably introduced copyright problems into multiple articles or files and assistance is needed in further review: See Wikipedia:Contributor copyright investigations.

Alternatives to deletion


In addition to nominating potential copyright infringements for deletion, you may:

  • Rewrite the article, excluding copyrighted text, including — unless you give credit — text authored by others on Wikipedia. This is done on a temporary page at Talk:PAGENAME/Temp so that the original, copyright-infringing version can be deleted by an administrator and the rewrite copied over. If the original turns out to be non-infringing, these two can be merged.
  • Write to the owner and ask for permission. Check whether they gave or will give permission (or maybe they in fact posted it here!). Also see Wikipedia:Example requests for permission, Wikipedia:Confirmation of permission.

Instructions for administrators


Pages should stay listed for a minimum of 7 days before they are checked and processed by administrators.

The templates collected at Template:CPC may be useful for administrators and OTRS agents noting resolution.
